ABSTRACT:
The composition of an earth formation is investigated by repetitively irradiating the formation with bursts of incident radiation and generating an unknown energy spectrum from radiation resulting from the interaction of the incident radiation with nuclei of the formation. A background energy spectrum is generated from radiation detected during a time interval adjacent to the interval in which the unknown energy spectrum is measured. A percentage of the background spectrum, shifted to have the best energy-versus-channel number match with that of the unknown spectrum, is then subtracted from the unknown spectrum to produce an improved, unknown spectrum substantially free of background contributions from which an improved, compensated, inelastic neutron interaction log may be generated.
